SECTION 2
LOCATING THE BOILER
2.A
Field Assembly
This boiler is shipped with an automatic vent damper that
must be assembled onto the vent collar on the top of the
boiler, and then plugged into the unit using the dedicated
harness.
2.B Boiler Placement
This boiler is design certified by CSA-International for
indoor installation on combustible flooring, in basements,
in closets, utility rooms or alcoves
. These units must
never be installed on carpeting.
1. This boiler is designed for indoor installations only
and should be located to provide clearances on all
sides for maintenance and inspection. See Figure
6. It should not be located in an area where leakage
of any connections will result in damage to the
area adjacent to the unit or to lower floors of the
structure. When such a location is not available, it is
recommended that a suitable drain pan, adequately
drained, be installed under the unit.
NOTE: For installation on combustible flooring.
NOTE: For Closet Installation Clearances, the
minimum clearance between hot water pipes
and combustible construction is 1” (2.5 cm.)
2. A minimum of 15” (381mm) access must be
available in front of the boiler for burner removal.
Consult local codes for clearances to hot water
pipes and accessories.
3. If the boiler is to be installed in a garage, all
burners and burner ignition devices must have a
minimum 18” (457mm) clearance above the floor.
4. Boilers may be installed in a closet as long as
all minimum clearances are followed, including
between the front of the boiler and the closet
door when it is closed. See Figure 6. Consult
the American National Standard Z21.13 for more
information concerning closet installations. In
Canada, refer to the latest edition of CSA-B149.1.
5. When vented vertically, the unit must be located
as close as practical to the vertical section of the
vent. When a power venter is used with a terminal
through a wall, and there is a potential for snow
accumulation, the terminal must be installed at an
appropriate level above grade or the maximum
expected snow line.
